I wanted to update my Android box TX2, so first I tried to use the PC, but my Android Tool didn't detect the box (No Device Found), so I tried the SD update method, so when I powered on the box with the resent button, it brought me to the recovery mode which include the option: Apply update from SD, so I chose this option, but no update file was found the SD card, I thought maybe because I unzipped the update file in the SD card, so I copied the zip file this time in the SD card, but not only I got an failed update after the box started to update, but also the box stuck in the Android logo when starting, so now I need to know if there is a way to fix the pc USB connection with the box using the USB cable in order for the Android Tool to detect the box, or if somebody provide a link for a good update file with the SD method. Thanks
